A lot of companies these days are using Slack for their internal communications. And can you blame them? Slack is easy to use and fast as hell (I promise you Slack didn't pay me to
say write this!). It was used at the company where I did my internship. I fell in love with Slack's simplicity. I used it every workday to ask simple questions to people who where out of the office, to send files around and so on...
During this internship we held daily stand-up meetings (a must for every Agile team). Sadly though we often forgot this because not everyone came in at the exact same time. To fix this, I configured an IFTTT rule that pushed the message
STANDUP MEETING to our general chat room on Slack when everyone was at the office. Easy and convenient!
